CHARLES L. DEPOLLIER, OF NEW YORK, AND EDWARD C. DUNCUFF, OF MOUNT VERNON, NEW YORK, ASSIGNORS TO DUBOIS WATCH CASE COMPANY, OF BROOKLYN, NEW

YORK, A CORPORATION OF NEW YORK.

WATCHCASE, 8w.

Application filed January 21, 1916.

To (ZZZ/1071,0770 it may concern:

Be it known that we, CHARLES L. Dnronm'na, a citizen of the United States, residing in the borough of Brooklyn of the city of New York, in the county of Kings, in the State of New York, and EDWARD G. DUNcUrF, a citizen of the United States, residing in the city of Mount Vernon, county of lVestchester, in the State of New York, have invented certain new and useful Improvements in Vatchcases, &c., of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates generally to convertible watches, that is, to watches which can be worn in different ways, as sautoire, chatelaine or wrist-watches, without having readily visible, when a watch is worn in one way, the devices by which it is secured in place when worn in another way. It is concerned particularly with devices by which the watch is to be secured to a ribbon to be worn as a sautoire watch, or to a ribbon or strap to be worn as a wrist-watch, but it will be obvious that the devices in which the invention is embodied may be of such size as to be adapted for use with a chain or otherwise, as may be desired.

The invention will be more fully ex plained hereinafter with reference to the accompanying drawing in which it is illustrated and in which,

Figure 1 shows a watch provided with the improved devices and secured thereby to a wrist-strap or ribbon. Figs. 2, 3 and 4: are detail views, on a larger scale, illus trating one form in which the invention may be expressed. Figs. 5, 6, 7 and 8 are similar views showing a dilferent embodiment of the invention. Figs. 9, 10 and 11 are similar views showing another embodiment of the invention.

In Fig. 1 of the drawingsis shown a watch at having a crown b for winding and setting, and diametrically opposite fastening or securing devices whereby it may be secured to a wrist-strap or ribbon a, but obviously it might be provided with only one securing device for use with a sautoire ribbon or a fob. The case of the watch, preferably the center 6, is formed at a convenient point, or at opposite points, as shown in each of the several figures of the Specification of Letters Patent.

drawing, with a recess or recesses c suitably shaped to receive the bars and links which, in each of the several en'ibodiments illustrated, constitute the securing device, the recess 0 in each instance being suit ably formed to receive the securing device snugly when the latter is in its closed or concealed position. The securing device in each instance comprises a transverse bar of suitable length for engagement with the strap or ribbon, and links by which the bar is connected to the watch-case in such manner as to permit the bar to be extended for use or to be folded, with the links, into the recess so that it will not be readily visible, when the device is not required for use.

In the embodiment of the invention illustrated in Figs. 2, 3, and 4t the bar f is pivotally connected at each end to a link f and each link is movably connected at its other end to the watch-case, within the recess e. As shown in these figures, the inner end of each link is pierced by a pin which is received and travels in slots 6 in the side walls of the recess. The bar may therefore be extended for engagement with the ribbon or strap, as shown in Figs. 1, 2 and 3, while remaining connected with the case through the links f, or it may be pressed back into the recess, out of sight from the side, as shown in Fig. 4, the pins f traveling in the slots 0 and permitting the links to lie down flat within the recess. The bar may be formed with a shallow groove or grooves f and the side walls of the recess may be cut away as at e to facilitate engagement of the bar by the fingernail in drawing it out.

In the construction shown in Figs. 5, 6, 7 and 8 the bar f is formed and pivotally connected at its ends to links 7 substantially as before, but the links 7, instead of having a sliding connection with the case, are pivoted directly to the case as indicated at 7, one at the extreme end of the recess 6' and the other at a point somewhat remote from the corresponding end of the recess, so that the links swing in parallel relation and in the same direction rather than in opposition, as in the construction shown in Figs. 2, 3 and 4. Figs. 5 and 6 show the device extended and Figs. 7 and 8 indicate it as folded within the recess.

The embodiment of the invention repre sented in Figs. 9, 10 and 11 is substantially like that represented in Figs. 5, 6, 7 and 8, but the links 7, although pivoted in the recess e as before, are not placed wholly at one side of the bar 7", as in the construction shown in Figs. 5, 6, 7 and 8, but are arranged as a pair, the bar f being received between the links of such pair when the device is folded into the recess, as shown in Fig. 10, while the link 7' which may be a solid link, is slotted at its end to receive the bar.

The mode of use of the device, when the watch is to be worn in one way or another, will be readily understood without further explanation.

We claim as our invention:

1. The combination with a Vatch-case having a recess of links movably secured at one end within the recess, and a transverse bar pivotally secured to the links at its ends, whereby the bar and links may be folded into the recess to become practically invisible or extended to permit the bar to be engaged by a strap or ribbon.

2. The combination with a watch-case having a recess of links pivotally secured within the recess, and a transverse bar pivotally secured at its ends to the links whereby the bar and links may be folded into the recess to become practically invisible or ex tended to permit the bar to be engaged by a strap or ribbon.

This specification si ned this 18th day of January, A. D. 1916.
